Radiator 1955-56 Chevy 6 Cyl w/ Trans Cooler

The ALLSTAR PERFORMANCE Radiator 1955-56 Chevy 6 Cyl with Trans Cooler (ALL30005) is a purpose-built cooling solution for classic Chevy fullsize cars of the mid-1950s. This aluminum radiator combines engine cooling capacity with integrated transmission oil cooling in a single compact unit, eliminating the need for separate cooler installation. The center inlet and passenger-side outlet configuration ensures proper flow direction through the original mounting points, making it a direct fit for 1955–1956 Chevy six-cylinder applications.

Constructed from aluminum with natural finish, this radiator measures 23.25 inches wide, 23.25 inches tall, and 2.25 inches deep—dimensions that align with original equipment specifications for these model years. The integrated oil cooler function maintains transmission fluid temperatures during sustained driving, which is critical for automatic transmissions that operate inefficiently when fluid temps exceed safe thresholds. The two-pass aluminum core design maximizes heat transfer while the robust construction withstands the demands of street driving and light performance use.

This radiator is ideal for hot rod builders and classic car enthusiasts restoring 1955–1956 Chevy fullsize sedans, coupes, and wagons equipped with inline-six engines. It serves both stock restorations that prioritize originality of appearance and modified builds where cooling capacity or transmission temperature management has become a concern. The combination of period-correct mounting and modern aluminum construction provides reliable cooling without requiring extensive custom fabrication or adaptation.

ALLSTAR PERFORMANCE specializes in cooling system components and radiators for classic American cars, making this unit a credible choice for authenticity-focused restoration work. The all-aluminum design resists corrosion better than older brass-core radiators, an advantage for long-term storage or vehicles exposed to salt air or humidity. Weighing 18.25 pounds, it remains light enough for original mounting brackets while delivering the thermal performance expected of modern manufacturing standards.
